.SH NAME
OSSL_PROVIDER\-base \- OpenSSL base provider
.SH DESCRIPTION
.IX Header "DESCRIPTION"
The OpenSSL base provider supplies the encoding for OpenSSL's
asymmetric cryptography.
.SS Properties
.IX Subsection "Properties"
The implementations in this provider specifically have this property
defined:
.IP """provider=base""" 4
.IX Item """provider=base"""
.PP
It may be used in a property query string with fetching functions.
.PP
It isn't mandatory to query for this property, except to make sure to get
implementations of this provider and none other.
.IP """type=parameters""" 4
.IX Item """type=parameters"""
.PD 0
.IP """type=private""" 4
.IX Item """type=private"""
.IP """type=public""" 4
.IX Item """type=public"""
.PD
.PP
These may be used in a property query string with fetching functions to select
which data are to be encoded.  Either the private key material, the public
key material or the domain parameters can be selected.
.IP """format=der""" 4
.IX Item """format=der"""
.PD 0
.IP """format=pem""" 4
.IX Item """format=pem"""
.IP """format=text""" 4
.IX Item """format=text"""
.PD
.PP
These may be used in a property query string with fetching functions to select
the encoding output format.  Either the DER, PEM and plaintext are
currently permitted.
.SH "OPERATIONS AND ALGORITHMS"
.IX Header "OPERATIONS AND ALGORITHMS"
The OpenSSL base provider supports these operations and algorithms:
.SS "Random Number Generation"
.IX Subsection "Random Number Generation"
.IP "SEED-SRC,  see \fBEVP_RAND\-SEED\-SRC\fR\|(7)" 4
.IX Item "SEED-SRC, see EVP_RAND-SEED-SRC"
.PD 0
.IP "JITTER,  see \fBEVP_RAND\-JITTER\fR\|(7)" 4
.IX Item "JITTER, see EVP_RAND-JITTER"
.PD
.PP
In addition to this provider, the "SEED-SRC" and "JITTER" algorithms
are also available in the default provider.
